But the front pages tell readers that a man who knew Joanna Yeates killed her. Are they facts? Well, no. But they are part of the police’s ploy. In a joint statement, David and Teresa Yeates say:

“Many of us are armchair detectives, but if this activity triggers anything please come forward… “

But what do we know? Chris Jefferies has been monstered. The media harped on about two killers. Anything else..?

“Has anyone you know had an unusual or inexplicable reaction? Was their behaviour unusual on the weekend of the 17th to the 19th of December, or through the past three weeks? Do you know someone who has been behaving out of character, either by actions or what is said, or not said? Do you know someone who has inexplicably become reclusive, quiet – or vocal?”

The parents do not speak off the cuff. They speak with the police. One killer is being sought. They apply the pressure. Mrs Yeates adds:

“Something apparently insignificant could trigger the killer to kill again. Please help us to identify the killer.”
